Parts of a Kitchen Cabinet: Every Component Named, From Toe Kick to Crown

The parts of a kitchen cabinet fall into seven groups: the box (two side panels or gables, a bottom deck, a top or stretchers, a back and a hanging rail), the toe kick under it, the face frame on framed cabinets (stiles, rails and a center stile), the door (its own stiles and rails around a center panel), the drawer (a face on the outside, a box on the inside), the hardware that moves them (hinges, slides, pulls) and the trim and interior that finish everything off. If you came here for one answer — the bottom of a cabinet is called the deck or bottom panel, and the recessed strip under it is the toe kick — you have it. The rest of this guide names every other piece, says what it does, and tells you which line on a spec sheet describes it.

We're Captivating Cabinets, an online dealer that ships assembled and RTA cabinetry nationwide and doesn't install, which means every question we field arrives without a cabinet in the room to point at. This is the vocabulary we use on the phone, walking from the outside of a base cabinet inward. Where a brand we carry publishes a real number for a part — the thickness of a gable, the size of a face frame, the name of a hinge — we quote it, because those are the numbers you'll see on a quote. For the wider dictionary of trade words and abbreviations, our cabinet terminology guide covers the words this anatomy tour doesn't.

One Cabinet, Seven Groups of Parts

Take a 24-inch-deep base cabinet — the workhorse under every countertop — and strip it in your mind. Pull the door off and you're looking at the face frame (or, on a frameless cabinet, straight into the opening). Pull the drawer out and it separates into a decorative front and a plain wooden box. Lift the whole thing away from the wall and you find a hanging rail across the back, a bottom panel a few inches above the floor, and a recessed notch under that panel where your toes go. Everything else in a kitchen — crown at the ceiling, light rail under the wall cabinets, a filler against the wall, a finished panel on the end of the run — is trim added around that one unit.

That gives us a natural order: box, toe kick, face frame, door, drawer, hardware, trim, interior. Two families of cabinet exist, and the vocabulary is nearly identical for both. A framed cabinet has a solid-wood frame glued to the front of the box; a frameless cabinet (also called full-access or European) does not, so its gables are thicker and the doors mount straight to them. We'll flag where the two diverge, and our framed vs frameless guide has the full argument for choosing one over the other.

The Box: Gables, Deck, Top, Back and Hanging Rail

The cabinet box — a lot of installers say carcass — is the structural shell everything else screws to. When a spec sheet says "all-plywood construction" or "furniture board sides," it's describing this shell and nothing else. Its five panels each have a name.

Gables, or side panels. The two vertical sides of the box. Gable is the cabinetmaker's word (it's the everyday term in Canada and in most frameless catalogs); American spec sheets more often say "sides" or "cabinet sides." The gable at the end of a run is the end gable, and because it's raw box material it usually gets a finished skin panel or a thicker decorative end panel on top — our skin panels and gables article covers that whole decision, so we won't repeat it here. On a frameless cabinet the gable is the load path: it carries the hinges, the drawer slides and the shelf pins directly, which is why frameless boxes run ⅝″ to ¾″ panels where framed boxes often make do with ½″. Of the lines we carry, Fabuwood Allure publishes a ½″ veneered plywood box, US Cabinet Depot's framed lines ½″ furniture-grade plywood, J&K ½″–⅝″ plywood, St. Martin ⅝″ plywood, and NOMA ¾″ plywood on its frameless boxes.

Deck, or bottom panel. The horizontal floor of the cabinet, and the answer to "what is the bottom of a cabinet called." On a base cabinet the deck sits above the toe-kick recess, so the inside floor of the cabinet is a few inches higher than the kitchen floor. On a wall cabinet the deck is the panel you see from below when you look up under it — the reason light rail molding exists, which we'll get to. Sink bases are the one place the deck's material really matters, because it's the panel that meets a leak first; a plywood deck survives a wet week, furniture board swells.

Top panel or stretchers. Wall cabinets have a full top so nothing falls behind them. Base cabinets usually don't: because a countertop covers them, most brands use two front-to-back or side-to-side strips called stretchers (or top rails) instead of a solid top. Stretchers hold the gables square and give the installer something to screw the countertop to. Neither approach is better; it's a wall-versus-base distinction, not a quality one.

Back panel. The rear of the box. It's typically thinner than the sides — ¼″ plywood on St. Martin and NOMA, for example, and Fabuwood's Ovela line grooves its back panel into the gables for rigidity. A thin back isn't a corner cut, because the back does not carry the cabinet's weight; the next part does.

Hanging rail, hang rail or nailer strip. A solid strip of wood or plywood, usually ¾″ thick, mounted horizontally across the inside top of the back (and often the bottom too). This is what the installer drives screws through into the wall studs, so it carries the loaded cabinet, dishes and all. The glossary entry for nailer strip has the detail; in conversation you'll hear all three names for the same part. If you're evaluating an RTA line, the hanging rail is the part to check for a snug fit after assembly, since a loose one is the difference between a cabinet on the wall and a cabinet on the floor.

Dust panel. A thin horizontal panel between stacked drawers so crumbs from one don't fall into the next. Not every line has them; where a brand does include one it's a small sign of semi-custom or custom-grade attention. See dust panel in the glossary.

How those panels are joined matters as much as what they're made of. Fabuwood lists its Allure assembly method as dowels and glue with pocket-screw joinery; Diamond's Edge series builds on a plywood box as standard. Cam locks and staples sit at the budget end. If the material words on a spec sheet are unfamiliar — plywood, furniture board, MDF, melamine — our materials and construction guide explains them one by one.

The Toe Kick and Kick Plate

The toe kick is the recessed notch at the floor line of a base or tall cabinet, and the reason you can stand at a counter without leaning forward. Typical dimensions are around 4″ to 4½″ tall and 3″ to 4″ deep. It's built into the cabinet's stated height, not added to it — a Fabuwood base cabinet, for example, is 34½″ tall with a 4½″ toe kick already included, which is why the standard 36″ counter height works out once a 1½″ countertop goes on. Our Fabuwood sizes and specs guide walks through that math.

The kick plate — also called the toe kick board, toe kick cover, or simply "TK" on a quote — is the finished strip that covers the recess after installation. It ships as a separate length of matching material and is cut on site, which is why it appears as its own line item rather than being part of each cabinet. Frameless lines sometimes handle this differently: Fabuwood's Illume sits on adjustable legs, while its sibling Ovela uses a recessed plywood toe kick like a framed cabinet, a difference our Illume vs Ovela comparison spells out.

The Face Frame: Stiles, Rails and Center Stile

On a framed cabinet, the face frame is a flat solid-wood frame glued and doweled to the front edges of the box. It stiffens the cabinet, hides the raw plywood edges, and gives the hinges a solid hardwood surface to bite into. It also narrows the opening slightly, which is the trade-off frameless construction exists to remove. Every brand we carry publishes it as a hardwood part: US Cabinet Depot's framed lines use ¾″ × 1¾″ solid hardwood, St. Martin's Heritage frames are ⅞″ thick by 1½″ wide, J&K specs 100% solid wood frames and Tribeca solid wood face frames.

The frame has three kinds of member, and their names are the most useful two words in this whole guide:

• Stiles are the vertical members, running the full height of the cabinet at the left and right edges.
• Rails are the horizontal members: a top rail, a bottom rail, and on a base cabinet with a drawer over a door, a mid rail between the two openings.
• The center stile (or mullion, in some catalogs) is the vertical divider between the two doors of a double-door cabinet. Both doors close against it. Some brands omit it for a wider opening — a butt-door configuration — which needs specific hinges and is worth asking about if you plan on storing wide trays in that cabinet.

The face frame is also where overlay and reveal are measured. Overlay is how much of the frame the closed door covers; the reveal is the strip of frame left visible between doors. Partial overlay shows a lot of frame, full overlay shows a sliver, and inset doors sit inside the frame so the whole frame reads as a reveal. That's its own decision with its own price implications, covered in our overlay styles guide; the part to remember here is simply that the frame is what all three styles are measured against.

The Door: Frame, Center Panel, Bevel and Edge Profile

A door borrows the face frame's vocabulary. A five-piece door — a shaker, a raised panel, a recessed panel — is built from two vertical stiles, a top and bottom rail, and a center panel captured in a groove between them. The joint that makes the groove is called cope and stick: the rail ends are shaped to lock into a matching profile on the stiles. Rail width is a design choice that brands publish; Mantra, for instance, lists 2¼″ rails on its Omni and Classic shakers and a 3″ rail on Spectra, and that quarter-inch or so is most of the difference between a "slim" and a "standard" shaker look. Rail width travels with the finish on that brand, which is why our Mantra cabinet colors guide talks about doors and colors in the same breath. A slab door has none of these parts: it's a single flat panel, which is why it's the natural fit for frameless cabinets and the odd one out in this section.

The center panel is the part most often made of something other than solid wood, and for good reason. Solid wood moves with humidity and cracks paint at the joints; an engineered panel doesn't. Fabuwood's Allure doors are solid wood frames around a ⅜″ MDF center panel; NOMA's are ⅞″ solid wood frames around an HDF panel; Tribeca's Americana door is five-piece MDF throughout. Why that is the right engineering rather than a cost cut — and where fiberboard genuinely loses to wood — is the subject of our guide to HDF and MDF cabinet doors. None of these is a downgrade on a painted door — it's the construction that keeps a painted shaker looking painted. On stained doors, a solid or veneered wood panel is what shows grain.

Bevel. A bevel is an angled cut where a square edge would otherwise be. On a raised-panel door the bevel is the sloped border of the center panel, which is what "raises" it toward the frame. On a slab door a reverse bevel is an inward angle cut along the top or side edge to make a finger grip, so the door opens without a pull — the usual route to a handle-less kitchen without adding channel hardware.

Edge profile. The shape milled into the outer edge of a door or drawer front: square, eased, ogee, and dozens of proprietary names. Diamond's Edge series is built around this part, offering its door styles with a choice of edge profiles. On most stock and semi-custom lines the profile is fixed per door style and not something you choose separately.

Two door variants earn their own names. A mullion door replaces the center panel with a frame for glass, divided by thin bars (mullions, or the lighter muntins). A tambour door isn't a frame-and-panel at all — it's a run of narrow slats on a flexible backing that rolls up a track, the door on an appliance garage. Our Fabuwood door styles guide shows how one manufacturer combines these parts into a catalog.

The Drawer: Face, Box and Bottom

Every drawer is two things bolted together, and the distinction matters when you read a spec sheet because the two parts are specified on different lines.

The drawer face — the same part is called the drawer front, drawer head, or, in British and Australian catalogs, the drawer fascia — is the decorative panel you see when the drawer is closed. It matches the door style and finish, and it's the part a spec sheet means by "5-piece drawer fronts" or "slab drawer fronts." A five-piece front is a miniature door, with its own stiles, rails and panel; a slab front is one flat piece. Both are common on the same shaker door: Mantra's Omni uses five-piece fronts and its Classic uses slab, and Fabuwood's Allure lists "5-piece recessed panel drawer fronts." Decorá goes further and offers its favourite doors in a five-piece drawer-front version specifically so the drawer stack reads as furniture. Our Decorá review covers how far a semi-custom catalog takes that idea. A false drawer front is a face with no box behind it — the panel under a sink, where the bowl occupies the space a drawer would.

The drawer box is the container behind the face: four sides and a bottom. Its two published specs are the side material and thickness and the corner joinery. Fabuwood Allure lists a ⅝″ solid wood dovetail drawer box; US Cabinet Depot's framed lines ⅝″ solid hardwood dovetail; St. Martin and NOMA ¾″ dovetailed solid birch with plywood bottoms; J&K, Tribeca, Mantra and Decorá all spec dovetail solid wood. The exception in our catalog is the metal drawer box: Fabuwood's Illume uses Blum Merivobox steel-sided drawers and US Cabinet Depot's frameless Palermo and Torino use metal-sided boxes. Those aren't inferior — they're a different European tradition — but they are a different part, and if you want wood inside the drawer you should say so. Why the dovetail matters, and how to spot a stapled box pretending to be one, is the subject of our dovetail drawers article.

The drawer bottom is the part nobody lists and everyone should ask about. A ¼″ or ⅜″ plywood bottom set into a groove in all four sides will hold a drawer of cast iron for decades; a thin hardboard bottom stapled to the underside will not. St. Martin publishes ⅜″ plywood bottoms on its drawer boxes, which is the kind of number you want to see.

Hardware: Hinges, Slides, Pulls

Hardware is the set of parts that move, and it's where brand names appear on a spec sheet, so it pays to know which part each name refers to.

Hinges. Almost every cabinet sold today uses a concealed hinge, also called a Euro hinge: a hinge you can't see when the door is closed. It has three parts. The hinge cup is the round housing pressed into a 35mm hole bored in the back of the door; the mounting plate is screwed to the face frame or, on a frameless cabinet, to the gable; and the arm clips the two together and carries the adjustment screws that let an installer align a door in three directions after hanging it. Soft-close is a damper built into the cup or arm. The names you'll meet on our brands' sheets: Fabuwood Allure lists hinges with Blumotion soft-close and Quick-Release technology; St. Martin and NOMA list Blum soft-close; US Cabinet Depot's framed lines list concealed 6-way adjustable soft-close hinges and its frameless lines Hettich Sensys 110° soft-close (the 110° is how far the door swings); Diamond uses MasterBrand's Smart Stop soft-close. If you want the case for paying attention to the brand on a hinge, our Blum hinges article makes it.

Drawer slides. Also called glides, runners or guides — four words, one part. A drawer slide is the track pair the box rides on, and its spec has three dimensions: where it mounts (undermount, hidden beneath the box, versus side-mount, visible on the box's sides), how far it opens (full extension brings the whole box out past the face frame; three-quarter extension leaves the back few inches inside), and how it closes (soft-close damping, self-close springs, or neither — a difference our soft-close vs self-closing guide explains). Undermount full-extension soft-close is the current standard across the lines we carry: Fabuwood Allure lists Blum Tandem plus Blumotion full-extension concealed runners, St. Martin and NOMA list Blum undermount soft-close full extension, US Cabinet Depot's framed lines undermount full-extension soft-close (its frameless lines rate their slides at 88–132 lb), and J&K and Mantra full-extension soft-close glides. A slide's load rating, where published, is worth more than its adjectives.

Pulls and knobs. The decorative pull or knob on the outside of the door is the one hardware part that is almost never included with a cabinet — it's ordered separately, and drilled on site or, on some lines, at the factory for a charge. The measurement that matters is the center-to-center distance between the two screw holes on a pull, because that's the number a replacement has to match. Handle-less kitchens skip this part entirely by using a reverse-bevel edge, a routed channel in the door, or a push-to-open latch instead.

Trim: Crown, Light Rail, Scribe, Fillers and End Panels

Nothing in this group is part of a cabinet. Trim is the set of separate pieces ordered alongside the cabinets to finish a run, and each one has a sibling article that covers it properly, so this section only names them and says where they go.

• Crown molding runs along the top of the wall cabinets, closing the gap to the ceiling or simply finishing the top edge. It's frequently stacked with a flat riser strip behind it to reach the ceiling.
• Light rail molding is the small profiled strip along the bottom front edge of the wall cabinets — under the deck we named earlier — that hides under-cabinet lights and their glare. Typically ¾″ to 1½″ tall.
• Scribe molding is a thin flexible strip fitted on site to close the gap between a cabinet and a wall or ceiling that isn't straight.
• Filler strips are flat finished boards, usually 3″ to 6″ wide, cut to fill the space between a cabinet and a wall or appliance so doors and drawers clear the obstruction. A fluted filler is the decorative version.
• End panels and skins dress the exposed end gable of a run, the island back, or the sides of a refrigerator or dishwasher opening.
• Kick plate, covered above, is trim too — it ships as loose lengths.

For the profiles, quantities and costs, our cabinet molding types guide covers crown, light rail and the rest; end panels, scribe and fillers explained sorts out which gap gets which piece; and the skin-panel article linked earlier handles finished sides. The one thing to take from this section: trim is where quotes go wrong, because these parts are easy to leave off and impossible to install without.

The Cabinet Interior: Shelves, Pins and Finished Insides

The cabinet interior is the surface you see with the door open — the inside faces of the gables, the deck and the back — and its finish is a real spec line. The brands we carry describe it three ways: a natural wood veneer interior (Fabuwood Allure and Ovela), a maple melamine interior (St. Martin and NOMA), a UV-coated plywood interior (US Cabinet Depot's framed lines), or a white linen interior (Fabuwood Illume). All are wipeable and all are normal; the difference is look, and it only matters much on glass-door or open cabinets, where some lines let you order a matching finished interior so the inside is the same colour as the door.

Shelves. An adjustable shelf rests on four shelf pins pushed into rows of holes bored in the gables — the 32mm-spaced pattern of the European system, which is why a shelf can move in fixed steps. A fixed shelf is set into a dado and doesn't move; you'll find one as the mid-shelf of a tall pantry, where it's doing structural work. Shelf thickness and edge treatment are the quiet quality tells: St. Martin lists ¾″ plywood shelves with a solid maple front edge, NOMA ¾″ plywood with a PVC edge, Tribeca ¾″ adjustable plywood, and US Cabinet Depot's frameless lines full-depth 18mm shelves, fully edge-banded. Edge banding is the thin strip glued over the raw front edge of a plywood or particleboard shelf; if it's peeling at delivery, that's a claim.

Every Part on a Spec Sheet: The Summary Table

Here is the whole cabinet in one table — the part, what it does, and the line on a manufacturer's spec sheet or your quote that describes it. If a spec sheet is silent on a part, that's a question for your designer, not a reason to assume the best.

Two vocabularies sit on a quote at once, and it helps to know which one you are looking at. The part names in the table above are cabinet nomenclature — the words for the physical pieces, and they are broadly consistent across the industry even where a brand prefers "side" to "gable." The letters beside each price are something else: SKU shorthand for the cabinet type and its dimensions, where B is a base, W a wall, SB a sink base, DB a drawer base and TK a toe-kick length, followed by the width and height in inches. Those letter codes vary by manufacturer and are decoded line by line in our SKU code guide; the wider dictionary of cabinet abbreviations and buying-process terms lives in our kitchen cabinet terminology guide. A quote that names the part and the code for every line is a quote you can check.

How the Same Parts Differ Across the Brands We Carry

The parts are the same in every catalog; the numbers attached to them are not. This is the same anatomy read across five of the lines we sell, from published spec tables, so you can see how much a single part can vary at different price points. Full tables for every line are in the spec books. Two of these five get a full write-up of their own: our St. Martin review covers Heritage, Vista and NOMA, and our J&K review covers the RTA side of the table.

Read the column for the box and the column for the drawer box together and the price ladder mostly explains itself. Notice, too, what "not published" means: not that the part is missing, only that the brand doesn't print a number for it. That's where a door sample and a direct question earn their keep — samples for every line are on our door sample page, and a physical door tells you the frame thickness, panel material and edge profile faster than any table.

Reading a Quote With This Vocabulary

Knowing the names is only useful if it changes what you ask for. Here's how we'd use this guide against a cabinet quote, ours or anyone's:

1. Find the box spec and the drawer box spec as two separate lines. "All-plywood construction" describes the gables and deck; it says nothing about the drawer box, which is a different part with its own material and joinery. A quote that is proud of one and silent on the other is telling you something.
2. Check that the hinge and slide are named, not just described. "Soft-close" is a feature; Blum, Hettich or Smart Stop is a part. Ask which.
3. Look for the loose parts. Kick plate, fillers, scribe, crown, light rail, end panels or skins. None are part of a cabinet, all are needed, and each should be its own line.
4. Ask what the center panel is made of if you're buying painted doors. MDF or HDF is the right answer for paint; it's not a shortcut.
5. Confirm the toe kick is in the height. A 34½″ base with the toe kick built in lands a 36″ counter; adding 4½″ on top plans for a counter you can't reach.
6. Ask about the drawer bottom and the hanging rail — the two parts no spec sheet advertises and the two that fail first when they're thin.
7. Decide which gables will be seen, and count the end panels before the order goes in rather than after the delivery arrives.

Trade buyers do this on every job, which is part of why the parts vocabulary exists in the first place: a contractor who says "gable," "kick" and "hang rail" gets an accurate quote in one pass. Through Captivating Pro, contractors and designers buy every line above at 20–40% below retail, with the same spec sheets behind every number.

Frequently Asked Questions

What are the parts of a cabinet called?

The box is made of gables (sides), a deck (bottom), a top or stretchers, a back panel and a hanging rail. Below it is the toe kick, covered by a kick plate. Framed cabinets add a face frame of stiles, rails and a center stile. The door has its own stiles, rails and center panel; the drawer has a face and a box; and the hardware is hinges, slides and pulls. Trim (crown, light rail, scribe, fillers, end panels) and the interior (shelves, pins, finish) complete the list.

What is the bottom of a cabinet called?

The bottom panel of a cabinet box is the deck, or simply the bottom or floor. On a base cabinet it sits a few inches above the kitchen floor; the recessed space under it is the toe kick, and the finished board that covers that recess is the kick plate or toe kick board. On a wall cabinet the deck is the panel you see from underneath, which light rail molding is designed to trim.

What is a gable on a cabinet?

A gable is a cabinet's side panel — the vertical structural panel of the box. The term is standard in Canada and in frameless catalogs; American spec sheets more often say "sides." The gable at the end of a run is the end gable, and because it's unfinished box material it normally gets a skin panel or decorative end panel. On frameless cabinets the gable carries the hinges, drawer slides and shelf pins directly, so it's thicker.

What is the difference between a drawer face and a drawer box?

The drawer face (also drawer front, drawer head or drawer fascia) is the decorative panel on the outside that matches the door style and finish. The drawer box is the plain wooden or metal container behind it that actually holds your things and rides on the slides. They're specified separately: the face is described with the door style, the box by its material, thickness and joinery, usually dovetail.

What is a skin panel, and is it the same as an end panel?

Both are finished panels applied to an exposed cabinet side so the raw gable matches the doors. A skin is a thin veneer-like panel that simply matches the finish; a decorative end panel is thicker and often shaped like a door, for a furniture look. Both do the same job, and one or the other belongs on any gable that faces a room. Our skin panels and gables article covers sizing, quantities and installation.

What is a door bevel?

A bevel is an angled cut where a square edge would otherwise be. On a raised-panel door it's the sloped border of the center panel that makes the panel stand proud of the frame. On a slab door, a reverse bevel is an inward-angled edge along the top or side that works as a finger grip, so the door opens without a pull. It's one of the standard routes to a handle-less kitchen.

What is the inside of a cabinet called, and what is it made of?

The cabinet interior is the inside surface of the gables, deck and back, plus the shelves. It's finished for wipeability, and the finish is a published spec: natural wood veneer on Fabuwood Allure and Ovela, maple melamine on St. Martin and NOMA, UV-coated plywood on US Cabinet Depot's framed lines, white linen on Fabuwood Illume. On glass-door cabinets some lines offer a matching interior in the door colour.

What are the parts of a cabinet door called?

A five-piece door has five: two vertical stiles, a top rail, a bottom rail, and a center panel captured in a groove between them, joined by a cope-and-stick profile. A slab door has none of these — it is one flat panel. The outer edge carries an edge profile, and on a raised-panel door the sloped border of the center panel is the bevel.

What is the strip at the top of a cabinet door frame called?

On a face frame and on a five-piece door, the horizontal members are rails and the vertical members are stiles, so the strip across the top is the top rail. The vertical strip between two doors on a double cabinet is the center stile. Those two words — stile for vertical, rail for horizontal — cover most of the frame-and-door vocabulary you'll meet on a spec sheet.
